Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples.
Example 1:
the utility model provides a piston internal mold cooperation structure, internal mold cooperation structure includes two limit fan 1, well fan 2 and drawing die frame 3, well fan 2 includes well fan I5, well fan II6 and well fan III7 from a left side to the right side in proper order, drawing die frame 3 below end strip spring 4 pushes down well fan I5 and well fan III7 respectively, drawing die frame is connected with well fan II through screw in the middle of the below, the both sides of well fan II6 are provided with dovetail I8 and dovetail II9 respectively, dovetail I8 and dovetail II9 are trapezoidal, and the two size is different, well fan I5 is provided with dovetail block I10 with dovetail I8 assorted with well fan II6 junction, well fan III7 is provided with dovetail block II11 with dovetail II9 assorted with well fan II6 junction, the length of dovetail I8 is greater than dovetail block I10, the length of dovetail block II9 is greater than dovetail block II 11. When the middle fan II starts to be lifted, the middle fan II moves firstly, the middle fans I and III do not move up and down, but move towards the middle, and when the end stop of the dovetail groove supports the lower end of the dovetail block, the middle fan II, the middle fan I and the middle fan III move upwards together.
The upper surface of the middle fan II6 is provided with two inclined bosses 12, and the sizes of the two inclined bosses 12 are different. The inclined bosses 12 are matched with inclined grooves 13 arranged on the top surfaces of the two side fans 1.
When the utility model is used, the drawing die frame is arranged on the casting machine, the side fan firstly enters the outer die cavity under the driving of the mechanical arm of the casting machine, the drawing die frame pushes 3 middle fans to move downwards under the action of the casting machine, because the positions of the middle fan I and the middle fan III are lower than that of the middle fan II in the lifting state, therefore, the middle fan I and the middle fan III firstly enter the outer die cavity, after the middle fan I and the middle fan III are in place, the outer side of the middle fan I and the middle fan III is propped against the outer die after in place, the outer mold is blocked and does not continuously move downwards any more, the dovetail block is connected with the dovetail block through the dovetail groove, the dovetail block slides in the dovetail groove, the middle fan II continuously moves downwards to separate the middle fan I and the middle fan III from left and right and is tightly matched with an inner cavity of the outer mold, meanwhile, 2 italic bosses on the upper part of the middle fan II are respectively inserted into 2 italic grooves on the side fan, the outer die drives the side fan to be closed together, and an independent mechanical arm outside the casting machine is used for pouring molten aluminum. After the piston blank is formed, the drawing die frame moves upwards, the middle fan II is driven to move upwards firstly, the stop springs on two sides of the drawing die frame press the middle fan I and the middle fan III to prevent the 3 middle fans from moving upwards together, the middle fan I and the middle fan III are translated towards the direction of the middle fan II simultaneously under the combined action of the stop springs, the dovetail grooves on two sides of the middle fan II support the lower ends of the dovetail blocks of the middle fan I and the middle fan III to drive the middle fan I and the middle fan III to move upwards together, and the production of the piston blank is completed.
